Abstract
A supercharger constructed in accordance to one example of the present disclosure includes a housing, first and second rotors, a bearing plate and a pair of sleeves. The first and second rotors are received in cylindrical overlapping chambers of the housing, the first rotor supported by a first rotor shaft, the second rotor supported by a second rotor shaft. The bearing plate is coupled to the housing and has an oil cavity side and an air cavity side. The bearing plate is formed of aluminum. The pair of sleeves can be received by the bearing plate and support respective bearings rotatably supporting respective first and second axle shafts. The pair of sleeves are formed of steel.

A supercharger comprising:
- a housing;
- a first rotor and a second rotor received in cylindrical overlapping chambers of the housing, the first rotor supported by a first rotor shaft, the second rotor supported by a second rotor shaft;
- and
- a bearing plate coupled to the housing and having an oil cavity side and an air cavity side, the bearing plate formed of aluminum;
- and
- a pair of sleeves received by the bearing plate and that support respective bearings rotatably supporting the respective first and second axle shafts, wherein the pair of sleeves are formed of steel.
A supercharger comprising:
- a housing having an inlet port and an outlet port;
- a first rotor and a second rotor received in cylindrical overlapping chambers of the housing, the first rotor supported by a first rotor shaft, the second rotor supported by a second rotor shaft;
- and
- a bearing plate coupled to the housing and having an oil cavity side and an air cavity side, wherein the air cavity side defines an inset portion that leads to the outlet port of the supercharger, the inset portion having pressure relief slots formed thereon corresponding to each of the first and second rotors and configured to minimize pressure and heat to improve isentropic efficiency of the supercharger.
